Description

Dialysis tube resetting device Technical Field The utility model relates to the technical field of medical appliances, in particular to a dialysis tube resetting device. Background The peritoneal dialysis patient needs to keep the dialysis catheter in the body for a long time, the dialysis catheter has two functions, the dialysis fluid is introduced into the abdominal cavity during dialysis, the in-vivo fluid is drained out of the body after the dialysis is finished, the dialysis tube which is kept in the body easily forms a floating tube under the action of the peritoneal dialysis fluid and intestinal peristalsis, and the floating tube can lead to unsmooth drainage of the peritoneal dialysis fluid, so that the dialysis tube needs to be reset after the floating tube occurs. For the repositioning of dialysis tubing, prior art CN220656070U proposes a peritoneal dialysis catheter repositioning device that utilizes a bendable head, which allows the device to be extended into the dialysis tubing during use, and then utilizes the bent head to reposition the dialysis tubing.
